Solar collectors, Solarwall and PV modules are integrated in only one part of the building as reported in figure 13 and 14. This solution has been proposed since it could be applied in any similar condition without changing the local architectural typologies.

Solar systems are installed close to the technical rooms in order to reduce distances and thus energy losses between solar surfaces and other parts of the systems, like boilers, inverters, batteries, and so on.

Solar surfaces are also easy to clean and maintain, since no particular machineries or stairs are needed. Attention is also been paid in the design of the support system of the PV modules to prevent vandalism or thefts.

5. Conclusion

The house design highlighted the potential of the whole building approach and of the use of energy efficient and solar technologies in improving the energy performance of a Mediterranean house. This has been recognized by the Regional Government of Lazio providing funding support for the construction of the house, which will be started in 2004. The house will monitored for a period of 10 years. Detailed cost analysis is still underway. This example is already stimulating interest among local contractor and technicians.
